My wife and I are in the preliminary stages of planning of planning our fourth trip to Europe during late December 2014 for about 16 days. We have been to most of western Europe on our previous trips. We are trying to come up with an ambitious itinerary, which includes Berlin, Prague, Kracow, Vienna, Munich, and Zermatt.
Please provide your feedback on what is realistically doable on this trip. We do not mind traveling by plane, train, or bus during the trip. Also, we need feedback on where to fly in and fly out of. We can easily fly out of Charlotte or Atlanta from the U.S.
Thanks
